Add a scrub bar for any video playing

Hi guys,

I really want to be able to have a scrub bar on my touchbar whenever ANY video is playing. Often times I watch videos for school on websites other than YouTube, Netflix, etc. And the only thing that comes up on my TouchBar is the link for the video. How can I make it so that a scroll bar comes up whenever there is a video playing?

Any Luck yet with this one ?
